' 10 a doorway a door, which in its vertical position will close thedoorway, and in its horizontal elevated position will projectr throughthe doorway to form an overhanglng canopy protection.

It is also an object to provide a swinging door 15 with means forsupporting the door so that it may travel bodily as well as swing, thebodily movev ment being guided by guides.

It is a further object to provide a one-piece panel door with guides forreceiving rollers located on the upper end of the door, said guidesbeing provided with horizontal channels for guiding the upper end of thedoor horizontally, and with vertical downward extensions, whereby thedoor may be moved vertically downwardly as it reaches its closingposition, the parts of the guides forming the downward extensionsserving to hold the upper end of the door against the door jambs.

These and other objects andv advantages will appear from the followingdescription taken in connection with the drawings.

Referring Ito the drawings:

Figure 1 is an inside elevation of one sideof the door and the door jambto which the door is attached, the door and the jamb'shown broken away.4

, FigureZ is a section on the line 2--2 of Figure 1. In this figure thedoor is in its closed position.

Figure 3 is a view similar to Figure 2 but with Vthe door elevated, dueto the inward opening movement. I

AFigure 4 is a view similar to Figures 2 and 3 but with the door in aposition intermediate that shown in Figure. 3 and its openhorizontalposition.

Figure 5 -is a section through the door showing it in its open position.

Figure 6 isa top plan view of the door and its operating mechanism,showing the adjacent wall structure in section.

Figure 7 isa section on the line 1-1 of Figure 1.

Figure 8 is a section on the line il--8` of Figure 1.

The door of this invention is adapted tobe used in connection withgarages, storage-rooms and the like, in which there is'an opening orpassageway provided on each side with a door jamb I, and across the topwith a lintel 2. Beneath the lintel and extending toward the inside ofthe building is a strip 3 suitably attached to the lintel in anysuitable manner. For the purpose of closing the passageway between thetwo door jambs a one-piece door 4 is provided.

Each door jamb has thereon an inwardly extending bracket 5 to which alink 6 is pivoted in- 10 vtermediate its ends. To one end of this link 6one end of a lever I is suitably pivoted, while the other end of thelever 1 is pivotally attached to `a bracket 8 attached to the door belowits middle point. To the other end of the link 6 is pivoted 15 a lever 9intermediate its ends. One end of this lever 9 is pivotally connectedtol one end of a link I I), which has its other end pivotally connectedto the lever 1 intermediate its ends. The other end of the lever 9 isprovided with a counterweight II.

When the.door is in its closed position it engages at each insideedge-with a plate or weather strip I 2, attached to the jambs of thedoor. These strips extend from the bottom of the doorway up- 25 ward toa point past the center line. Cooperating with the weather strips I2 areplates I3 attached to the door and adapted to engage the jambsV abovethe strips I2.

The door is provided at its upper end, at each 30 edge, with a bracketI4, on which there is mounted a roller I5. On the upper edge of the dooris a strip I6, which is adapted to engage the insideedge of the lintel 2and the top edge of the strip 3 when the door is in a closed position,as shown 35 in Figures 1 and 2. The rollers I5 are adapted to travel inhorizontal guides I1 in the form of channel tracks. Each guide issupported at its inner end by means of a bracket I8, suitably attachedto some part of the building. 'I'he ends 40 of the guides adjacent thedoorway are supported by means of brackets I9. These brackets havehorizontal passageways or horizontal channels 20, corresponding in shapeto and in alignment with the channel parts of the trackways or guidesIl,

`and downwardly extending channelways 2| into which the door rollersenter just before the door reaches its closed position.

In the final closing of the door thedoor moves. downwardly, with therollers in the downwardly 50 extending channelways 2| so that when thedoor is closed the brackets I9 serve to prevent the inward movement ofthe upper end of the door. The lowerl end of the door is held againstinward movement by means of the plates I2. The door 55 is prevented frommoving outwardly by means of the plates I3 engaging the jambs, and bymeans of the rollers I5 engaging the lower parts of the brackets E9.

Operation When it is desired to open the door it is first moved upwardlyfrom the position shown in Figure 2 to that shown in Figure 3. Duringthis part of the operation of the door the rollers move upwardly in thechannelways 2l until the rollers reach a position for movement in thechannels of the guides il. This upward movement of the door is aided bythe counterweight it, which acts in a plane parallel to the door forraising the door.

During this upward movement of the door the link 6 serves as a lever,the counterweight acting on one end of the lever to move the doorconnected to the other end of the lever. The initial upward movement maybe brought about by applying downward pressure to the counterweight orby lifting the door. When the door gets in the position shown in Figure3 a movement of the counterweight to the right or a movement of theklower end of the door to the left causes the whole door mechanism andits operating lever system to move about the pivot of the link G. Inthis movement the rollers travel along the guides il.

Figure 4 shows the door in what might be called the second stage of itsopening movement. A continued movement of the counterweight to the rightand downward, with the lower end of the door moving to the left andupward will bring the door to its open position, as shown in Figure 5.In this position the door is horizontally disposed,

with its lower end projecting out through the doorway to provide acanopy structure. The amount of this projection depends upon theposition of the bracket 8 with regard to its distance from the lower endof the door. With this bracket closer to the lower end of the door thedoor projects alesser distance through the doorway. With this bracketnear the center of the door the projection is greater.

The lever and counterweight mechanism may be attached to one or bothsides of the door. If such mechanism is attached to one side of the doora heavier counterweight would be necessary, whereas if attached to bothsides of the door a lighter counterweight would be sufficient.

By providing means for lifting the door bodily it is possible to lift itabove any collection of ice, snow or other material before swinging ittransversely of the door opening. By providing a counterweight that willrst move the door vertically in conjunction with the guide and then moveit transversely of the door opening, it is possible to utilize a singleweight for the compound movement of first lifting the door and thenmoving it into a horizontal position over the door opening.
